感谢Molodos大佬创造的优秀模型，我在他的基础上增加了三种不同形状的齿轮，因而能画出更多有趣的图像，你也可以发挥自己的想象力，做出更多有意思的图形来，方法很简单：把你想要加入的形状与齿轮组合，把这些形状的类型修改为负零件，就可以打出你想要的图形了。

Thanks to the excellent model created by the Molodos boss, I added three different shapes of gears to his base, so that you can draw more interesting images, and you can also use your imagination to make more interesting shapes, the method is very simple: combine the shapes you want to add with the gears, modify the type of these shapes to negative parts, and you can create the shape you want.
